Why won't song album covers change?

[AC Question]

This is becoming infuriating now. I have installed Sum 41's "All the Good ****" album from iTunes and I now want to change the album information to make the tracks appear in their original albums. I have changed all of the information to the proper information on iTunes and I have removed the songs completely from my device. Now, when I try to reinstall them, it puts them into three different albums all entitled "All The Good ****". I've tried to install multiple different music players and I have gotten the same result with all of them. With all of the other albums, (Does this Look Infected? etc.) it's worked perfectly well, and with other artists (such as REO Speedwagon), changing the information of their greatest hits album's songs to the information of the original works perfectly fine.
